New Web Based Watch/Warning/Advisory Map Colors Why change the colors? The previous map process allowed only 30 colors to be used. This caused complaints when we tried to use one color for several different watch/warning/advisory products. The new map process allows than 80 colors (one for each product). In theory, this allows us to convey more information to the users

The new colors were baselined from suggestions from web usability experts. They are less "glarey" and toned down to be easier on the eyes;

The increase of colors allowed products to be grouped by hue; For instance frost and freeze are blue, colors usually associated with the cold.
